  53 # @qemu:        The version of QEMU.  By current convention, a micro
  54 #               version of 50 signifies a development branch.  A micro version
  55 #               greater than or equal to 90 signifies a release candidate for
  56 #               the next minor version.  A micro version of less than 50
  57 #               signifies a stable release.
  58 #
  59 # @package:     QEMU will always set this field to an empty string.  Downstream
  60 #               versions of QEMU should set this to a non-empty string.  The
  61 #               exact format depends on the downstream however it highly
  62 #               recommended that a unique name is used.
